To all, whomitmag concern l f Be it known that I,- TIIoMAs NATHAN RUs-SELL, a citizen of the United States, residing in Chicago, in the countyof Cookand State of Illinoishave inventeda new and useful VImprovementin Car-Roofs, of ,which the followingfis a specification.v

` The invention relates to ca'r roofs in which separatemetal sheetsrest,with some freedom for horizontal yielding or movement, ona top sheathingor suitable framework,

Vandare joined together by upstanding seams formed bythe upwardly bentside edges ofV the sheets loosely but securelyinterengaged withpseamcaps to form water-tight seams,v

4said seams extendingfromthe ridge to the eaves of the roof.

V'It is an object ofiny invention jto eliminate side fasciae so that thegoods-containing :bodyof the car may be made as wide as possible andstill go safely through tunnel cle-arings;v a further object of theinvention iste securethe eaves edges of the roof sheets .on topgof andentirely within the outer side lines of the carv and'independent oftheeX- y.treme sdeedges of :the roof sheathing or frame; afurther object isto permit, in such a narrowed construction as thatlabove lmentioned, ofindividual horizontal play of the roof sheets., VVso as to preventstrains on the sheets and ontheir securing means.

With such objects in viewas well -asother advantages which mayv be-incident to the `use ofthe improvements, the invention con-V sistsinthe parts and combinations thereof V'hereinafter set forth andclaimed, lwith the vunderstanding thatthe several necessaryelementsconstituting the same may be4 varied in proportions andarrangement without departing from the nature and scope of theinvention,

In order to make the invention more clearly understood there are shownin the accompanying drawings means'i'or carrying the same into practicaleffect, without limit- Ving the improvements, in their usefulapplications, to` the particular constructions "which, for. the purposeof explanation, have `tlieieaves of the car. v Y Y Fig. l.

flashing, partly broken away.

Fig. 4 is av section on. line IV-IV of Fig. 5is a vertical sectionacross the ridge of the roof.

Fig. 6 is a section on line VI-VI of Fig. l, looking toward the eaves,the top sheathing, the side'plate and theside sheathing being omitted.

Referring. to the drawings, 1 is a side plate of the roof frame, 2 theside sheathing, and 3 the top sheathing. The latter is V,formed at theeaves with a recess 4L for the curing means.

5 is an eaves hook strip secured to the to sheathing and side plateinthe recess 4 by nails 6 which are ,driven down through the topsheathing and into the side plate. With said hook strips are looselyengaged hooks 7 which consist of downwardly and inwardly portions of theends of the roof sheets.Y i Y fr With this loose'y eaves seam iscombined an eaves flashing Vand fascia element consist ing of a verticalflange 8, which is secured to the side of the car by nails 9, and aninwardly andv upwardlyY inclined flange 10 which enters the seam abovethe hook strip 5 and belowthe roof sheet hook 7 so as not tointerferewith the functions of said seam lbut so as to exclude anyleakage from the jointswhere the metal parts come against thesheathings. The inner edge of 'the flashing is iipturned as shown at l1to insurethe back flow of any water which may be dashed into the seamunder theV roof sheets.

The upstanding and uniting seam of the roof sheets l2g`is shown at 13and preferably comprises aninverted U-shapedseam element 14; lformed onthe ad]l acentedges ofthe roof sheets, which elements engage over theupstanding flanges l5 of a tubularseam cap 16,1so thatthe arched top Vofthe cap incloses all of said parts 14 and 15 (Fig.

4:) and the roof sheets and cap can only 'be assembled and separated byendwise sliding in the direction of the length of the cap.

Itlwill be seenV that the structure of the pairing the security of theseam.

The eaves end of the seam 13 is inclosed Y and somewhat looselysecuredby a seam clip V18 having lateral flanges 19 and fingers 23,which engage above and conne the hori j zontal portions of the 'roofsheets'at the Vsides of the seam. 211 is an inwardly eX- tending flangeof the clip 18 which, to-` gether with vthe lingers 23, partly encircle,engage beneath and support the outer end ,of the seam cap so as to takethe weight of the seam elements and prevent it from being imposed on thesliding joint formed by the flanges 5 and 7 of the hook strip 'and roofsheet. The seam clipalso comprises a vertical shank 20 which is securedto the roof'franie by a bolt 21 passing through the sidesheathing andside plate'and by a nail 22 `which maintains thefproper verticalposition of the seam clip. v j j ,j

My improvement effects a material saving in thel elimination ofthefascia, andV any increase of cost due to greater width of the car bodygoes directly to increase in the'capacity of the car. Y

The eaves flashing is less liable to injury when itisapplied directly onVthe car body instead of on a projecting partflike a fascia. and theflashing takes the place of affaseia, and is in effect a fasciaelementin confining the'upper edge of the side sheathing. l

By this construction replacement and `re-v pairs of the roof sheetsandtheir'connected parts arev greatly facilitated, withsaving of timeand labor. Y

lVhat is claimed is-` j 1. In a cai' roof,ithe combination of a roofframe, a top 'sheathing carried thereby, roof sheets united in a looseseam which. permits individual movement of each sheet, the eaves ends ofthe roof sheets being formed with downwardly and inwardly bent hookedflanges, an eaves hook strip attached :to the body of the car near theeaves and formed rectly to theside sheathing andin'closing andsupporting the onterend of the seani Levens? cap and loosely confiningthe eaves ends of the roof sheets.

2. In a car roof, the combination of a roof frame, a top sheathingcarried thereby, roof' sheets having upstandingV downwardly hooked sideflanges, a seam cap having inwardly turned and upwardly hooked sideflanges which are engaged with the said Vflanges of a pair of adjacentroof sheets to form a loose seam, the eaves ends of the roof sheetsbeing formed vwith downwardly and inwardly bent hooked flanges, aneaveshook strip Vattached on the topV of thetop Y sheathing near the eavesand formed with outwardly extendingjhooked flanges which are looselyengaged with those of the roof side sheathing of the car and having atop flange which enters the eavesseam above a'portion of the eaves hookstrip and below the hooked flange of the roof sheets, and a seam clipattached directly to the side sheathing and inclosing and supporting theouterend of the seam cap and loosely conlining the eaves ends of theroof'sheets.

'3.In a car roof, the combination of a roof frame, a topy sheathingcarried thereby, roof sheets having upstanding downwardly hooked sideflanges, a seam cap having inwardly turned and upwardly hooked sideflanges which are engaged with the said flanges of a pair of adjacentroof sheets to form a loose seam, the eaves ends of the roofsheets beingformed with downwardly and inwardly bent hooked flanges, an eaves hookstriphaving an outwardly extending flange attached on the top of the topsheathing near the eaves and formed with outwardly extendingjhookedllanges which are loosely engaged with those of the roof` sheets,

sheets, an eaves flashing having a vertical flange which is directlyengaged Vwith theY an eaves flashingfhaving'a vertical flange fining theeaves ends of the roof sheets.

el. ln a car roof, the combination of a roof frame, a top sheathingcarried thereby, roof sheets united in a loose seain which perniitsindividualmovement of each sheet, the eaves ends` or" the roof sheetsbeing Vformed with downwardly and inwardly bent hooked flanges, an eaveshook vstrip secured to the top sheathing well withinl the eaves line ofthe car and formed with outwardly extending hooked flanges which Aareloosely engagedwith those of the I"roofsheets, and a structurallyindependent eaves vflashing secured directly to the side 4sheathing of:the

car independently of the hook strip and having a vertical flange thatdepends from the eaves line and atop flange that enters the eaves seamabove a portion of the eaves hook strip and below the hooked flange ofthe roof sheets, substantially as specified. y

5. In a car roof, the combination of a roof frame, a top sheathingcarried thereby, roof sheets united in a loose seam which permitsindividual movement of each sheet, the eaves ends of the roof sheetsbeing formed with downwardly and inwardly bent hooked fianges, an eaveshook strip secured to the top sheathing well within the eaves line ofthe car and formed with outwardly extending hooked flanges which areloosely enl. gaged with those of the roof sheets, astructurally-independent eaves flashing secured directly to the sidesheathing of the car and having a vertical flange that depends 'from theeaves line and a top Harige that enters the eaves seam above av portionof y l the eaves hook strip and below the hooked flange of the roofsheets, and a seam clip attached directly to the side sheathing andinclosing and supporting the outer end of the seam cap and looselyconfining the eaves ends of the roof sheets7 substantially as Specified.

6. In a car roof having a roof frame, a top sheathing carried thereby,and roof sheets adapted to be united in a loose seam which permitsindividual movement of each sheet, the eaves ends of the car sheetsbeing formed with downwardly and inwardly bent hooked flanges: an eaves'hook strip embodying a substantially flat member having a horizontalbottom flange which is secured on the top sheathing and terminating wellwithin the Veaves line of the car, said member having an outwardlyextending hooked flange adapted to loosely engage the roof sheet eavesflanging and to accommodate a flashing strip interposed between saidroof sheet flanging and the aforesaid Substantially flat member -of suchhook strip; substantially as specified.

7. In a car roof, in combination, a metallic Yfascia element, sidesheathing directly on which said fascia element is applied S0 as toconfine the same, a roof frame to which thel side sheathing is confined,roof sheets united-in a loose seam allowing individual movement of thesheets relative to the eaves of the car, and a longitudinal eaves hookstrip which confines the eaves edges of the roof sheets in a loose seampermitting them to have longitudinal and transverse movement, the upperpart of said fascia element being inserted under the eaves ends of theroof sheets and into the hook of said eaves hook strip.

In testimony whereof I have hereunto set my hand.
